The principle of structural reciprocity: history, properties and design issues

Pugnale, Alberto, Parigi, Dario, Sassone, Mario & Kirkegaard, Poul Henning

September 2011 | Conference Paper

This paper deals with the principle of structural reciprocity, considering its origins in both Occidental and Orient culture and aiming to highlight the definition, main characteristics and interesting aspects of such concept referring to its application to the world of construction. Issues spanning from history, form-finding and morphology, structural behaviour...

Workshop di costruzione architettonica: l’interazione tra forma e struttura nella ricerca e didattica del progetto

Pugnale, Alberto, Deregibus, Carlo, Sassone, Mario & Kirkegaard

May 2011 | Conference Paper

Il rapporto che in architettura lega forma e struttura è di particolare interesse sia nella ricerca sui temi del ‘non-standard’ (Migayrou 2003), focalizzati per lo più sullo studio della gestione parametrica del progetto, sulla fabbricazione a controllo numerico dei suoi elementi, nota come File-To-Factory o più recentemente Digital Crafting, e...

On the Optimal Design of Glass Grid Shells with Planar Quadrilateral Elements

Sassone, Mario & Pugnale, Alberto

December 2010 | Article

This paper presents an optimization procedure for the solution of the planarity problem, a requirement of grid shells with four or more sides faces that need of having four adjacent nodes laying on a plane in order to use plane glass slabs as cladding elements. It can be satisfied by...

New conceptual design tools: towards designers as software customizers

Pugnale, Alberto, Holst, Malene Kirstine & Kirkegaard, Poul Henning

November 2010 | Conference Paper

This paper aims to discuss recent approaches in using more and more frequently computer tools as supports for the conceptual design phase of the architectural project. The present state-of-the-art about software as a conceptual design tool could be summarized in two parallel tendencies. On the one hand, the main software...

The church of Longuelo by Pino Pizzigoni: Design and construction of an experimental structure

Deregibus, Carlo & Pugnale, Alberto

January 2010 | Article

This paper presents a critical study about the church of Longuelo (Italy), designed in 1966 by Giuseppe “Pino” Pizzigoni (1901–1967), an Italian architect who lived and worked in Bergamo. He began his studies on shell structures in the 1950s and many of his buildings show outstanding skills in conceiving and...

Computational morphogenesis in architecture: the cost optimization of free-form grid shells

Basso, Paolo, Del Grosso, Andrea, Pugnale, Alberto & Sassone, Mario

December 2009 | Article

The optimization problem related to the tessellation of free-form grid shells is presented in this paper. This kind of structure is generally composed of a supporting grid that defines the geometry of a large number of cladding elements that are always different from each other. From the construction point of...
